What this shows Huntsman's Innovation Score is 54.2/100 (top 8% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Huntsman?

Each dot is one of Huntsman’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Huntsman’s own 13.2 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Huntsman's grants concentrate

Huntsman Petrochemical LLC is a focused PatentsView assignee: 44 CPC subclasses with 54.1% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2019 (10 grants) versus a trough of 2 in 2020. By volume, Huntsman sits between Flexible Steel Lacing Company and Johnson Matthey PLC.

Huntsman's three-year grant acceleration

Huntsman Petrochemical LLC shows 19 grants in 2022–2024 against only 16 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
